Graduate Student Spotlight: Lucia Contreras

Ana Lucia Contreras Porras (Lucia) came to CPULD from San Jose, Costa Rica where her family, including two siblings, still reside. She completed her bachelors in Industrial Production Engineering at the Tecnologico de Costa Rica. After graduating with her bachelors, she discovered an interest in data analysis which was fostered by her last job – when she spoke with Dr. Laszlo Horvath about the opportunities here, Lucia felt it was a good combination of her previous degree and her newfound interest in data analysis.

Lucia told us that one of the reasons she chose to join CPULD is because of “Virginia Tech's commitment to innovation, state-of-the-art technology, and its extensive research in sustainable biomaterials made it the ideal choice for pursuing advanced studies and a career focused on the whole packaging system. CPULD offered a unique opportunity to work in a highly specialized and influential research center in the field of packaging and unit load design.”

Lucia told us about the research she’s conducting for her Master’s degree: “My current research will develop a model to estimate the number of wood pallets in circulation inside the United States. After this research, it will be possible to determine the impact of these wood pallets on the environment more accurately and will help to improve and optimize future production and use of this valuable and basic product essential for the transportation of good and products around the world.” Her research project is sponsored by the Pallet Foundation of the National Wood Pallet and Container Association.

She went more in depth by explaining that “through my master's thesis, I aim to utilize econometric analysis and material flow analysis to estimate the total number of wooden pallets in circulation in the United States. This research is crucial for a comprehensive understanding of the sustainability and environmental impact of wooden pallets. As trees capture CO2 during their lifespan, this embedded carbon in wooden pallets is a significant factor in assessing their environmental footprint. Currently, industry estimates suggest a wide range (between 1.8 to 2.6 billion pallets), but no scientific study exists in this area. I expect my research to provide a more accurate and detailed account of the total number of wooden pallets in circulation, enabling a more precise evaluation of their environmental impact.”

In order to complete her research, Lucia will initiate data collection on historical inputs and outputs relevant to the wooden pallet supply chain. “As some data may be unavailable for certain years, I will then construct an econometric prediction model to estimate missing values based on their correlation with independent economic variables. Subsequently, I will conduct a material flow analysis, incorporating the predicted values, to estimate the accumulation of wooden pallets over the years. The research process will be meticulous, involving data analysis, model development, and the application of both econometric and material flow analysis techniques.”

“This information is vital for making informed decisions regarding sustainability practices within the industry. It will enable stakeholders to quantify and reduce the carbon footprint associated with wooden pallets, fostering more environmentally-friendly practices and contributing to the industry's overall commitment to sustainability.”

Lucia already has learned a lot through her research and work as a CPULD lab technician. “The most helpful knowledge and skills I have been learning is a holistic understanding of pallets, packaging, and material handling. This interdisciplinary approach is essential for addressing complex challenges in the field and developing comprehensive, sustainable solutions.” Lucia believes that “the best part of my time at VT, so far, has been the invaluable combination of academic excellence and hands-on experiences. The university's commitment to cutting-edge research, interdisciplinary collaboration, and real-world applications has made my educational journey fulfilling and enriching.”

Although she does not yet have a job lined up for after graduation in 2025, Lucia knows what type of work she’d like to seek out. “I am actively exploring opportunities that align with my academic background in industrial engineering, my master's degree in sustainable biomaterials, and my experiences working at CPULD. I anticipate engaging in many tasks relating to research and data analysis. This may involve collaborating with cross-functional teams, conducting experiments or analyses, and staying updated on industry trends and advancements. I also expect to play a role in decision-making processes that contribute to the overall sustainability goals of the organization.”

Lucia keeps active and when she isn’t working or studying she enjoys hiking, particularly the Huckleberry Trail, reading or listening to music while surrounded by nature, and learning to cook new recipes. If she had to pick one food to eat for the rest of her life, she’d pick french fries. And, one of her favorite animals is the meerkat “a small mongoose-like mammal. While not large or physically powerful individually, meerkats use their agility and quick movements for hunting and protection. They are more reliant on their cooperative behavior than physical strength.”
